Sensory nerve action potentials in patients with peripheral nerve lesions.
In 1949 Dawson and Scott described a method of examining sensory impulses in human peripheral nerves. By their technique, the median or ulnar nerve at the level of the wrist was stimulated electrically using single shocks, and the action potential of the afferent volley recorded through surface electrodes placed over the nerve trunk at a higher level in the arm. The afferent volley contained bo...
متن کاملThe recording of nerve action potentials through skin in man.
Electrical stimulation of peripheral nerve in man has been shown to produce cerebral responses (Dawson, 1947), and analysis of these responses has made clear the need for some means of investigating the nature of the sensory afferent volleys concerned. Experiments carried out in 1945 suggested that it was sometimes possible to record through the skin action potentials in the ulnar nerve of one ...
متن کاملProperties of action potentials from insect motor nerve fibres.
Extracellular recording from small nerve branches provides a method for recording from several nerve fibres simultaneously. This is extremely desirable in studying the organization of a neuronal system. Furthermore, extracellular records are insensitive to small movements, are stable over long periods, and can easily be repeated with subsequent experimental animals. They also involve relatively...
متن کاملSensory transduction in peripheral nerve axons elicits ectopic action potentials.
Sensory properties of unmyelinated axons in the isolated rat sciatic nerve have been revealed previously by measuring stimulated neuropeptide release in response to noxious stimuli. In addition, axonal sensitization by inflammatory mediators has been demonstrated and shown to depend on the heat- and proton-activated ion channel transient receptor potential vanilloid receptor-1. It was unclear w...
متن کاملAction currents, internodal potentials, and extracellular records of myelinated mammalian nerve fibers derived from node potentials.
The potential distribution within the internodal axon of mammalian nerve fibers is derived by applying known node potential waveforms to the ends of an equivalent circuit model of the internode. The complete spatial/temporal profile of action potentials synthesized from the internodal profiles is used to compute the node current waveforn, and the extracellular action potential around fibers cap...
